<div class="moz-cite-prefix">I am not aware of any uBlox LEA-6P?<br>
<br>
I have and use regularly NEO-6P though, which has PPP and carrier
phase output.<br>
The only drawback of NEO6P is that it uses a simple crystal
instead of a TCXO so the Doppler values will be generally quite
high.<br>
That does not impact the carrier phase output quality however: in
zero baseline mode -in very good visibility conditions- "static"
gives me just a few mm variance and zero mean.<br>
<br>
As I mentioned ealier in PPP mode it does not make sense to talk
about rover and base as it is a _standalone_ positioning mode.<br>
<br>
The hacked version of RTKLIB for NV08C is actually here:<br>

released document here:<br>

<div class="moz-cite-prefix">Well, now, I've seen the LEA-6P units
are standalone PPP. But RTKLib has kinematic mode which seems
to use 2 units and this "differential".<br>
<br>
I did download the patched version of rtknavi that has a PPP
fix.<br>
I discovered that the PPP "Static" for determining the base
station location was pretty stable- however, it determines the
location for the "rover" only, so I just swapped the rover and
base port #'s to determine the static base location.<br>
<br>
When I selected PPP Kinematic, the fix jumps several meters back
and forth rapidly, but never seemed to stabilize much, and the
noise wasn't really centered on the true location either.<br>
<br>
I ordered the NV08C-CSM units, BTW. These new kids on the block
are GPS AND GLONASS, Galileo, Compass, and <span style="color:

standard accuracy, and a few months back the mfg released
firmware to expose the RAW pseudorange data. Michele Bavaro
thinks highly of them, and there's a hacked version of RTKLib
for them: <br>

So, this should be fun! <br>

The first is differential, the second standalone. <br>
